Abstract
The concept of spatial smoothing is first extended to a rectangular planar array and a two-dimensional (2-D) search function is formed to estimate the source of directions. To avoid performing a 2-D search, an approach based on two one-dimensional (1-D) searches is also discussed. This approach uses rows and columns of the rectangular array to perform 1-D searches. To match the data obtained, a 2-D verification is then performed. Computer simulation results for both approaches, based on the MUSIC method, are presented.Keywords
